brother-sister ice dancing combo stealing sochi. They've pursued the olympic dream together all their lives. Amy robach. Let's go back to her. They're adorable, Amy. They truly are. If you have been tracking the olympics on Twitter, you surely know the shibutanis, Alex and Maia. The rest of the world saw them in action and have quickly fallen in love. They're the reigning king and queen of the ice. Meryl Davis and Charlie Wyatt setting a record in the ice dance beating defending gold medalists Tessa virtue and Scott Mauer. Another pair skoal the hearts of Americans. Alex and Maia shibutani. A respectable ninth place. 2-year-old Alex and 19-year-old Maia have earned the nickname the shib sibs. Who coined that phrase? I think the fans. We kind of picked up on it. We appreciate at the they came up with a nickname. We're lucky that shib rhymes with sibs. Reporter: Give people an idea of how much together time you have had over the years. Definitely, a lot. We spend time together off-ice. We pretty hit much have always gotten along. Most arguments and disagreements come from skating-based things. We both have good ideas. Stooims it's just sorting through those that K we can run into trouble. Reporter: They can add budding movie directors to their resumes. They have filmed and posted videos to their youtube page. Two rising stars keeping it all in the family. When you finish your dance, do you look for your parents in the crowd? If we can find them. The first thing we do is hug. That's our thing. After we're done, we're like, we did it. Reporter: It's over. Time for food. Reporter: Yes, and that food, apparently, is McDonald's, which we have been partaking in, I'll be honest. They skated to "The best is yet to come" by Michael Buble. He was so excited, he tweeted. Maia tweeted back, so honored that you saw us skate. Thank you for being part of our olympic performance. They're going to be ice dancing tonight to a Michael Jackson medley. Can't wait for that competition.
